Application filed February My invention is an improvedpaper dispcnsing device. v v

In my copending application, Serial No. 599,795, I have disclosed. a paper dispenser.

The objectionto thisdevice is'that when the paper is drawn out of the frame, and the bale is in the forwardposition, any decrease in the pull on said paper will cause the bale V to return to the rear position, thus destroy iu ing the effect of the machine which is to provide a surplus tag of paper. I j j r The object of this invention is to provide a catch for the halewhereby said bale is held in the operating position until the paper has been cut at which time the bale is released.

Another object of my invention is to pro vide a means wherebythe paper roll is kept in'a central position between the-two supportingposts. V

In the drawing inwhich my invention is illustrated:

Figure 1 is a transverse sectional View of my paper dispenser. t

Figure 2 is a side View of the same.

Figure 3 is an enlarged fragmentary sectional view of the bale catch.

Figure 4 is a fragmentary plan view of the bale catch. r Figure 5 is aside View of the paper roll 31) supporting shaft and thecentralizing washer secured thereto.

Figure 6 is an end view of the same. Referring more particularly to the drawing: the numerals 1 and 2 indicate a pairof upright roll supporting posts which are joined at the top by a horizontal bar 3 and secured at their base to a suitable surface.

Detaehably mounted on the posts 1 and 2 is a paper guide frame 4 which comprises side walls 5 and 6. The walls 5 and 6 are secured to the posts 1 and 2 at their lower end by bolts extending through ears 7 and 8 on the walls 5 and 6 respectively and into the posts 1 and 2..

A downwardly inclined guide plate 9 is secured to the sides 5 and 6 and a hook 10 is formed on the upper end of said guide which is adapted to hook over the bar 3 and thereby hold the frame 4 in position therein.

A bale 11 is mounted in the frame 4 across a 20. 1923. Serial No. 1320,20?

through slots 13"- in the sides and to be supported by plates 13 secured to the sides after the bale has been placed; and counterweights13 are secured to theends thereof be low the journals. to keep said bale normally in a vertical position. 1

Thefront wall of th'e'frame 4.is formed in two sections 14 and 15; the upper section 14 is securely fastened to the sides 5 and 6 while the lower section is pivoted thereto in the following manner: Metal plates 16. are securedto the ends of the section 15, which plates are pivoted at 1''? to the sides 5 and6. Theplates 16- extend upwardly froinsection 15 adjacent the section 14, and within the fram'e4. "7 Pivoted to the tops of each of the. plates 16 are lugs 18 which are adapted to engage fingers 19 which extend from each end of the friction member 12. Stop plates 20 are securedto the sides '5 and 6 and extend into the path of the section 15 to limit its forward movement. A knife 21 is securedto. the lower edge of the ,SGCUOII 15 against which the paper is torn. "Asthe paper is drawnhorizontally out of the frame 4 the section15is'swungoutwardly and the plates As the bale 11moves-,

16 move rearwardly. forward the fingers 19'slip u'nder'the lugs 18 and are held by the latter as longas the kmfe 21 is pressed forward by the paper as shown in Figure 3. After the paper is torn the section 15 tends to drop back into the position indicated in Figure 1 and during its return motion the lugs 18 first slightly de press the fingers 19 and then lose their hold on the same so that the bale is free to swing back into its vertical position. A pair of rollers 22 and 23 are journaled adjacent the bar 3 to guide the paper. 'A pressure bar 24 rests against the paper roll to limit the unreeling thereof.

It is very essential that the paper he kept in a central position between the posts 1 and 2. To accomplish this I provide a pair of discs 25 which fit over the end ofthe sup porting shaft 26 against the ends of the paper roll and between said roll and the posts 1 and 2.

The slack forming mechanism may be applied tomachines for intermittently feeding webs of paper or other'inaterial, without cutting the web adjacent the section 15 by omittingthe knife 21. In this general ap-- loo plication the rollers 22 and'23 would function as in guidesand the outlet between the guide plate ,9 and the section function as an out guide, and the friction contact member 12 functions as a movable web carrier. v

The operation of such a paper feed is as follows Presuming the position of the paper is as shown in Figurel, when tension is put on the loose hanging end by pulling it the paper is drawn tight against the web carrier 12 and swings it to the position shown in Figure 3, where it is latched and held while there is tension on the web; lWhen the tension on the web is removed by stopping the pulling the carrier 12 may move back to its first position. Thus when there is no tension on the web it occupies a path, the shortest between the in and out guides, which may be likened to one sideof a triangle. When the web is pulled it follows a path, as shown in Figure 3 a much longer distance between the in and out guides, which may be likened to the other two sides of the triangle: and as two sides of a triangle are longer than the third side, when the tension on the web is removed and the carrier moves to the position of Figure 1 a slack is produced.

Having described my invention, I claim 1, In a paper dispenser, a frame, paper supporting posts, means for securing said frame to said posts, said frame having side walls and a front wall, a bale pivoted in said side Walls over which the paper is adapted to travel and move forwardly when the pa per is withdrawn, means for returning said bale to its rear position when the paper is re leased, saidlfront wall being formed with an upper section and a lower section, said lower section being pivoted to the side walls, plates secured to said lower section, lugs pivoted to saidplates, fingers secured to said bale which are adapted to be engaged by said lugs when the bale is in the forward position with the paper being withdrawn.

2. In a paper dispenser of the character described, means for supporting a roll of paper, a yoke pivoted and weighted at its free ends to normally present its cross-member above the roll 50 as to allow the end of the paper to be guided thereover and frictionallyengaging the paper so as to swing downward with the same as the latter is unrolled, a cutting edge for the paper, and a pivoted support for the latter adapted to have its lower section swung forward by the paper while its upper section swings backward into engagement with the yoke for holding the latter during the cutting action.

3. In a paper dispenser of the character described, means for supporting a roll of paper, a yoke pivoted and weighted at its free ends to normally present its cross-member above the roll so as'to allow the end of the paper to be guided thereover and frictionally engaging the paper-so as to swing downward with the same as the latter unrolled, a cutting edge for the paper, a pivoted support for the latter comprising a lower. section adapted to be swung fem 'ardly by the paper, and arms extending above the pivot having lugs thereon and fingers extending from the yoke adapted to be en gaged by the lugs as the cutting edge is swung forward forcutting action. i In testimony whereof I aflix my signature.
